Car GPS Navigation
An automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses a GPS navigation device to acquire position data to locate the user on a road in the unit's map database. Using the road database, the unit can give directions to other locations along roads also in its database. Dead reckoning using distance data from sensors attached to the drivetrain (a system of dynamics), a gyroscope and an accelerometer can be used for greater reliability, as GPS signal loss or multipath can occur due to urban canyons or tunnels.
